Abstract

A flow-rate regulator unit (1) has an insert housing (2) which is insertable into a fluid line and in which a plurality of throughflow paths are provided, in at least one throughflow path of which in each case one flow-rate regulator (3, 4, 5) which regulates the amount of fluid flowing therethrough per time unit to a pressure-independent determined throughflow value is disposed, and in at least one further throughflow path of which in each case one closing valve (6) which under the pressure of the inflowing fluid is movable counter to a restoring force from an open position into a closing position is provided. The at least one flow-rate regulator (3, 4, 5) and the at least one closing valve (6) in each case have one annular throttle body or valve body (8, 9, 10; 7) of an elastic material, respectively, which under pressure of an impinging fluid is deformed in such a manner that the at least one flow-rate regulator (3, 4, 5) constricts a regulating gap and the at least one closing valve (6) closes at least one valve opening (11). The flow-rate regulator unit in the insert housing (2) has a first annular duct (12) which delimits a housing face of the insert housing (2), in which housing face at least two inboard annular ducts (13, 14, 15) are provided, the center of which in each case is disposed outside the housing face which is delimited by the other inboard annular ducts (13, 14, 15).
